Application lil-ed September 21, V1925. Serial No. 57,547.

This invention relates to stoves and more particularly to oil stoves. f lt is customary in oil stoves employing Wicks to have the burners arranged'in a straight line so that they are all easily accessible from the front yof the stove for the purpose of lighting the burners and for cleaning. It is one of the objects ofthijs invention to provide an improved arrange mentof burners Ain Which's'ome are located behind those at'the front of the stove, this arrangement affording design that is shorter and more compact than the lstoves novsT commonly used.

i It is a furtheriobject 0f the invention to so'arrange the burners that any of them may be conveniently?movedto the front of the stove for' the purposeof lighting and cleaning and also to permit the use'of any particular' burner with diiferent openings inthe v stove top'.

A further object of the invention is to provide a more compact burner arrangement, than has been heretofore' used, in which the fuel reservoir vis locatedb'etween the burners so that all of them may be uniforinlyfsupplied with fuel;

`A further object of the invention is to pro vide a'construction inf which the fuel'reservoir is located betiveen the burners andv yetthoroughly insulated from the'` heat that is generated inthe burners.

' Other ob'ects'of the invention and the feav my invention,l certain parts .being broken Y away and other parts being'shown in section Fig; 2'is al section on'the line2 2 of v Fig. 1;

Fig. 3f is an enlarged vertical section lthrough the'fuel reservoir; and, j the yline 4-4 of "Fig 4 is a section on Fig. 1.

In the drawings have illustrated the application of my invention to a stove having-v four"burners which are arranged in' the I form offa square, the burners beingfindicated at 10, 11, 12 and 13.5 The details "of vconstruction ofthe burners are not shown `1n lthe :drawings as they form no part ofthe present invention but-Yitf Willbe understood'l that ofthe usual forms offvvick:omisov y called, Wickless burners may be used. lThe burners are enclosed in a square casing14 having the doorsl 15 at 'the front thereof which may be opened to permita'ccess to the burners and to the fuel reservoir. jThe top of the stove is indicated at 16 and has the usual openings 17 over the different burners.V The casing y14 is supported onlegs 18 and rods 19 extend diagonally across the interior ofthe casing between'the corners thereof, and support, at the center of the casing, a step-bearing 20. i

A block 21 is supported on the step-bear ing 20 and has a trunnion 22 cooperating therewith so that the blockg21'may `be r0- tated. Fuel supply pipes 23 extend radially from the block 21 and Vsupport thediferent burners. y D y Y LA fuel basinor sump-24 `is supported on thejblock 21 by means of af pipe 25 fuel being fed through the pipe'25 and the ports 26, in the block 21, to kthe different pipes 23. The sump 24 is arranged ina central chainber Vwhich is formed fby the Walls" 27, and

l28, these Walls being spaced apart to provide a jacket space 29 through Which airis permitted yto circulate. The Walls 27 vand" 28 are "preferably of cylindrical forni and the top of the chamber 80, Which'is enclosed thereby, as Well as'tothe'upper end of the jacket space.29,are closed by a cover 31 hat# ing anupwardly projecting vflange 32 Which is rotatably Varranged Vin a central opening in the top 16.A A perforated cap 33-is fitted in the Harige 32'to close'the opening therein. The cover 31 has a` peripheral 'flange 34 which lits over the Wall 28:

The Walls 27 and 28v are supported on the pipes 23 and held in properly spaced relation vby thef` members 85 "and bolts 36.' A

doorway is formed in the Walls 27 `and 28 and is normally yclosed bythe double-Walled door 37 which yishin'gedfto. the Wall' 28, as indicated at'38, and-is secured'n closed positionby means 'of the button'or latch 39. At

40 I have indicated a ring or handle on the door 37,by means of which it may be conveniently opened and closed. v Y

A fuel reservoir 41 Which may be -of the usual' construction consisting of an inverted glass bottle having afcheckr valve 42, is supported on the sump 24, as indicated in `Figs. 3 -and 4,v and this'reservoir may/be provided with a hoop43 havingan Aoutwardly proj ecting lug 44 thereon adapted to engage with a hook 45 on the door 37 for the purpose of supporting the reservoir 41 in an upright position.

IVhen it is desired to'remove or replace `the reservoir 41, the door 37 is swung open Amaintenance of the reservoir 41 in the upright position and to properly support it on the door 37, when the latter is open, a rest 46 may be provided on the door near the lower end of the reservoir. When the reservoir is removed from the sump 24, by opening the door 37, the valve 42 is automatically closed and when the reservoir is replaced on the sump, by closing this door, the valve 42 is automatically opened on account of engaging with the bottomof the sump, according to the usual practice. v

The upper part ofthe wall 28 isprovided with a series of openings 47 to' permit air to circulate upwardly through the jacket space 29 and be discharged through the perforations in the cap 33. The space 29 is open at the lower ends of the walls 27 and 28 to permit the relatively cool air from below the stove to enter the space 29 and the circulation of this cool air through the jacket of the chamber 30 effectively insulates the latter from the heat of the burners. A series of openings 48 may be provided in the top 16,v around the cap 33 for the purpose of Ventilating the space above the cover 31.

By the improved construction which I have devised the fuel yreservoir andthe burners being supported on the block 21 are freely rotatable as a unit so that any of the burners may be brought to the frontof the stove for the purpose of lighting or cleaning them. After any' particular burner has been lighted it may be swung to a position below one of the openings 17, at the rear of the stove, so that in this manner, I have provided a compact arrangement which has all of the convenience, so far as accessibility is concerned, of the ordinary arrangement in which all of the burners are arranged in a line close tol the front of the stove. By having the fuel reservoir at the center of the stovev the supply pipes for conveying the fuel to the vdifferent burners may be all ofV thesame length and therefore provide for a uniform supply of fuel to all of the burners. It will also be noted that in rotating the group of burners the fuel supply connections are in nowise disturbed. 1 l

The construction which I have devised Y'any ofthe burners to be used with any yof the openings in the top-of the stove so that, in

case any particular burner is out of order, the other burners may be arranged, as desired, under any three of the openings 17.
